Título

DEVELOPMENT AND APPLICATION OF REVERSE SYSTEMATIC REVIEW ON EPIDEMIOLOGICAL AND CLINICAL ASPECTS OF LAPAROSCOPIC RADICAL PROSTATECTOMY.

Resumo

Context: Evidence-based medicine (EBM) was widely used in the context of diverse surgical treatments through several systematic reviews (SR). Despite the high level of evidence from these reviews, the specificity of the analyzed outcomes makes it difficult to establish the state of maturity of the analyzed technique neglecting significant bias.
Objective: To describe a novel SR methodology based on a temporal population analysis in a Reverse Systematic Review utilizing the case of well-established laparoscopic radical prostatectomy (LRP).
Evidence Acquisition: A systematized search was performed in order to obtain the primary studies feeding SR for the composition of a complete database, covering geographical, bibliometric and clinical-surgical variables. Quantitative, qualitative and temporal correlations of studies variables were performed to determine trends regarding results, geographic distribution and bibliometrics to delineate the development and trends of LRP between 2000 and 2017.
Evidence Synthesis: Among a total of 353 SR found, 40 were included and provided 238 primary studies elected to the database composition. An accumulation of studies was found on the Europe-USA axis predominantly in 4 preeminent scientific journals, which scientifically influenced the profile of publications, mainly until 2011 when interest clearly migrates to robotic assisted surgery (RARP) reducing the influence of these centers in the development of LRP in an upfront reversal in the standard of publications with a clear shift between LRP and RARP studies. Operative time, blood loss and conversion to open surgery showed trend to reduction and only biochemical recurrence (among PENTAFECTA) positively correlated with the year of publication, all with stabilization throughout the period.
Conclusion: The Reverse Systematic Review proved to be feasible and effective in demonstrating the evolution of a surgical technique, outlining its "Natural History”, which is not captured in the standard SR. In addition, it allowed to identify the presence of scientific influencers and potential biases in the composition of the best evidence in the literature, as well as to trace the curves of development until its technical-scientific maturity. Further studies to test the reproducibility of this methodology may aid in the comparison of diverse surgical techniques.
